Molecular Characterization and Genetic Diversity of Haplogroup E Human Lice in Guinea, West Africa.

, the head louse, is an obligate blood-sucking ectoparasite that occurs in six divergent mitochondrial clades (A, D, B, F, C and E). Several studies reported the presence of different pathogenic agents in head lice specimens collected worldwide. These findings suggest that head louse could be a dangerous vector and a serious public health problem.

Epidemiology of chronic kidney diseases in the Republic of Guinea; future dialysis needs.

Background: Chronic kidney disease (CKD) is increasing worldwide and can lead to end-stage renal disease (ESRD).

Objectives: Because few patients with ESRD in the Republic of Guinea have access to haemodialysis, we retrospectively evaluated the prevalence of CKD, ESRD and access to supportive therapies.

Patients And Methods: 579 CKD patients (304 males; mean age: 44 ± 16 years) were admitted into Conakry nephrology department, the only centre in the Republic of Guinea, between 2009 and 2013.

Quality of life of patients with end-stage renal disease in Guinea.

This questionnaire-based study included 69 patients from the Republic of Guinea with end-stage renal disease (ESRD) and was conducted over 12 months. The factors that affected their quality of life (QoL) were determined. The included ESRD patients had an estimated creatinine clearance (CCr) of <15 mL/minute using MDRD formula.

Use of antivenoms for the treatment of envenomation by Elapidae snakes in Guinea, Sub-Saharan Africa.

Background: In Guinea Elapids are responsible for 20% of envenomations. The associated case fatality rate (CFR) ranged 15-27%, irrespective of treatment.

Results: We studied 77 neurotoxic envenomations divided in 3 groups: a set of patients that received only traditional or symptomatic treatments, and two other groups that received either 2 or 4 initial vials of Antivipmyn® Africa renewed as necessary.

[Life quality in patients at terminal stage of chronic renal failure with no access to dialysis].

A transversal prospective study of 69 patients with terminal stage renal disease covering a 12 month period - 1 January to 31 December 2010 - was conducted; the objective was to determine factors affecting their quality of life. This is a questionnaire study covering a 12 month period. The study group were patients with ESRD whose clearance of creatinin were less than 15ml/min.

Tick-borne rickettsiae in Guinea and Liberia.

While the high seroprevalence for the rickettsiae that cause spotted fevers and the multiple pathogenic rickettsiae is known, the data on the distribution of rickettsial diseases in Africa are often incomplete. We collected ticks from domestic or wild animals (generally a source of bushmeat) that were in contact with humans in 2 neighboring countries of tropical West Africa, Guinea and Liberia. In total, 382 ticks representing 6 species were collected in Liberia and 655 ticks representing 7 species were collected in Guinea.
